Well, you're right! Assuming that Urban Legends is not wrong, and I trust
them for all of the virus hoaxes going around.

As they said in their article, the style was an excellent mimicry of
Vonnegut's style, so much so that he apparently "...wished that (he) had
delivered it."

Still, as with the authenticity of Socrates' words in the Platonic
dialogues, the 'authority', or purported authority, for me, means a lot less
than whether or not what was said makes sense.

In this case, "Vonnegut's" comments were, for me, pure entertainment. Had
they been of poor quality or obvious nonsense, I would have felt bad about
attributing them to Vonnegut. But, the sunscreen, I think we really need to
trust the author on that one.
